I have a Lenovo thinkcentre M90 with onboard audio Realtek Alc662 and surround Creative inspire T6100. I have only 2 ch sound. I have sound only from front speakers and subwoofer.

0 - Front Left
1 - Front Right
2 - Unused
3 - Unused
4 - Unused
5 - Unused

My Pulseaudio daemon.conf has enable-lfe-remixing = yes

default-sample-channels = 6
default-channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe

Pulseaudio manager

Default sample type : s16le 6ch 44100Hz
Default Sink: alsa_output.pci-0000_00_1b.0.analog-stereo

alsa_output.pci-0000_00_1b.0.analog-stereo
Sample type: s16le 2ch 44100Hz
Channel map: front-left,front-right

/etc/default/speech-dispatcher has Run=No

I've tried adding options snd-hda-intel model=3stack-6ch to /etc/modprobe.d/alsa-base.conf, but no result

I've tried adding options snd-hda-intel index=0 model=3stack-6ch to /etc/modprobe.d/alsa-base.conf; nothing again.

I've tried editing /etc/pulse/default.pa

load-module module-alsa-sink device_id=0 channels=5 channel_map=.......

Nothing again.

I've tried editing /.asoundrc

pcm.sndcard{
type hw
card 0
device 1
channels 6
}

NOTHING

pcm.!default {
type plug
slave.pcm “surround51″
slave.channels 6
route_policy duplicate
}

NOTHING AND bunch of other configs - STILL THE SAME

This is my Alsamixer

Any suggestions to fix the problem?

0

We're going to begin by asking the obvious questions:

  1. Have you tried playing back any surround sound sources?
  2. Your first step should be from here: https://help.ubuntu.com/community/DigitalAC-3Pulseaudio

I was able to use that method to get surround sound working out of SPDIF on a similar audio chipset.

  • This should be a comment - please don't write an answer to ask for clarification from OP! – Zanna Jun 25 '17 at 4:58
  • Ive just tried the link you gave me . Still same 2 ch sound - rear left - rear right and lfe . Sitll dont have surround 5.1 in pulse audio control settings. Any other suggestions ? – Mihail Mihaylov Jun 25 '17 at 21:11
  • I really need other suggestion ! Help please – Mihail Mihaylov Jun 27 '17 at 17:30
